' In Great Britain January 12, 1933 29 Claims.

This invention relates'to machines for shaping uppers over lasts, and more particularly to machines havingmeans for pulling the upper over the last and for laying its marginal portion in- 5. wardly over an insole or sole onthe last and for fastening it in tensioned condition. The invention is herein illustrated as applied to a machine, of the same general type as disclosed in Letters Patent No. 1,510,851, granted on October 7, 1924, upon an application of Arthur E. Jerram and Joseph Gouldbourn, but it is to be understood that it is also applicable to machines of other types.

Machines of the type illustrated in the abovementioned Letters Patent are provided with a plurality of grippers for pulling the upper over a last at the end of the toe and the sides of the forepart, and are provided also with overlaying andfastening devices which are moved inwardly into positions for inserting upper-holding fas- ,tening's at the end of the toe and the sides of the forepart after the pulling of the upper, these devices including wipers which wipe the marginal portion of the upper inwardly over the shoe bottom preparatory to the fastening-inserting operation. Such machines often include, for example, five upper-pulling grippers, one at the end of the toe and two at each side of the forepart, and means for driving seven fastenings, one at the end of the toe and three at each side of the forepart, to fasten the upper in pulled-over position. The present invention provides an improved construction such that a machine having, for example, means for driving seven upper-holding fastenings as above described, may drive the reamost .side fastenings, i. e., those located farthest from the end of the toe, in locations nearer the waist portion of the shoe than customary heretofore, without danger of undue crowding of surplus upper material into the waist portion of the shoe as the marginal portion of the upper is laid or wiped inwardly over the insole or other shoe bottom part (hereinafter frequently referred to generically as the sole) preparatory to the fastening-inserting operation. For the purposes in view the construction shown comprises, in addition to members movable as heretofore with the side fastening devices to lay or wipe the marginal portion of the upper inwardly over the sole at the sides of the forepart, other overlaying members so arranged and operated asito engage the upper in locations farther from the end of the toe than the above-mentioned members and. to lay the upper over the sole in such 55; manner as to prevent the crowding of surplus upper material into the waist portion of the shoe. As illustrated, these additional members engagethe upper at the ball portion of the shoe in locations slightly farther from the end of the toe than the locations of the rearmostside fastenings, and are moved widthwise of the shoe with components of movement also toward'the toe end of the shoe in angular relation to the directions of movement of the side overlaying members that operate nearer the end of the toe, the latter being so constructed and arranged as to engage the upper only at the toe portion at substantial distances'from the additional mem-- bers. In further accordance with the illustrative disclosure the additional overlaying memhere are moved inwardly into engagement with the upper whilethe upper is still held by the grippers and before the overlaying members that move with the fastening devices and operate at the sides of the toe engage the upper, the additional members being controlled by springs which impel them inwardly over. the shoe bottom immediately uponthe release of the upper by the grippers. As also herein shown, and in accordance with a further feature of the invention, the so additional overlaying members are carried by side clamping devices which in machines of the ilrespectively to these devices and members.

The aboveand other-features of theinvention, including various novel details .of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out inthe claims.

Since the invention, as above stated, is herein illustrated as applied to a machine of the wellknown type, disclosed in the previously mentioned Letters Patent, only such parts of the machine as it is necessary to refer to for an understanding of the invention will be hereinafter mentioned.

As above suggested, the machine herein shown has five grippers for pulling the upper over the forepart of. the last and means for driving seven tacks through the upper and the sole at the forepart of the last bottom to fasten the upper in pulled-over position. The last with an upper and a sole assembled thereon is supported against the pull of the grippers by a work support or sole rest 1 (Figs. 2 and 4) on which the work is positioned by the operator with the last bottom downward and its toe end pointing upwardly toward the rear of the machine. Near the beginning of the operation of the machine a heel rest 3 (Fig. 1) is moved lengthwise of the last into engagement with the heel end of the shoe to assist in maintaining the work in proper position. One of the five grippers, indicated at 5 in Figs. 1, 2 and 4, is positioned rearwardly of the work support 1 for operation upon the upper at the extreme toe end of the last, and two grippers 7 are arranged to operate on the upper respectively at the opposite sides of the last in locations at or near the ends of the toe tip line if the upper isprovided with a toe tip. The other two grippers 9 are arranged to operate on the upper respectively at the opposite sides of-the last in locations about an inch nearer the heel end of the upper, for example, than the grippers '7 and at approximately the same distance from the toe end of the last as the ball line of the shoe. It will be understood that the grippers, which are normally open to receive the upper materials when the machine is at rest, are moved in downwardly and rearwardly inclined directions relatively to the inclined last so as to pull the upper in directions substantially perpendicular to the plane of the last bottom, these movements being effected by camoperated levers which act yieldingly on the grippers through springs adjustablein strength. The five grippers are also arranged to move inwardly toward each other after they have pulled the upper heightwise of the last, to draw the margin of the upper inwardly across the edge of the sole. The machine is further equipped with a pair of upper-clamping arms 11 (Figs. 1 and 2) arranged to swing inwardly toward each other about horizontal pivots 13 (Fig. 1) after the grippers have pulled the upper heightwise of the last, and each of these arms carries, as usual in machines of the illustrated type, a curved self adjusting rubber pad 15 which serves to clamp the upper against the side of the last in the region of the tip line and fairly close to the bottom of the last, and a self-adjusting rubber pad 17 which serves to clamp the upper against the top face of the forepart of the last also in the region of the tip line. These pads clamp the upper against the last before the grippers release the upper, and by their pressure prevent the upper from recovering its original slackened condition when the grippers release it preparatory to the tack-driving operation.

The machine herein shown is also provided, like prior machines, with three tacker arms having at their upper ends tack holders from which tacks are driven upwardly into the shoe bottom to fasten the upper in pulled-over position after the upper has been released by the grippers. The tacks. are fed to the tack holders by means of substantially the same character as disclosed in Letters Patent No. 1,921,099, granted on August 8, 1933 upon an application of W. T. B. Roberts,

this means including tubes 19 which lead from tack-supplying means 21 (Fig. 1). One of these tacker arms, shown at 23 in Fig. 1, is mounted at the rear of the toe gripper 5 and is provided with means for driving a single tack at the toe end of the shoe. The arm 23 is mounted to swing forwardly about a horizontal axis 25 and carries a yieldable wiper 27 which, as the arm is swung forwardly, engages the extreme toe end of the upper near the edge of the sole and wipes the marginal portion of the upper inwardly over the sole before the tack is driven. A soft rubber block 29 carried by the arm 23 serves to limit the forward movement of the arm by contact with the toe end or the shoe. The other two tacker arms, indicated at 31 in Figs. 1 and 4, are mounted one at each side of the machine in locations farther ou.twardly from the Work support than the side grippers, and each of these tacker arms carries at its upper end three tack holders arranged in a series lengthwise of the shoe and provided with tack pockets 32 (Figs. 4, 6 and 8) from which tacks are driven upwardly into the shoe bottom to fasten the upper at the side of the forepart. These two tacker arms are swung inwardly toward each other into positions for the tack-driving operation, the directions of their inward movements being approximately perpendicular to that portion of the edge of the shoe bottom which is located near the toe tip line so that the arms have components of movement lengthwise of the shoe toward its heel end as well as widthwise of the shoe. The locations of the side tacks in relation to the shoe, as the machine herein shown is constructed, may be inferred from the positions of the tack pockets 32 in Fig. 8, and are such that one tack at each side is slightly nearer the end of the toe than the tip line, another is slightly farther from the end of the toe than the tip line, and the remaining tack is about an inch nearer the heel end of the shoe than the last-mentioned tack.

For wiping the marginal portion of the upper inwardly over the sole at the opposite sides of the it shoe bottom preparatory to the tack-driving operation the machine herein shown is provided with novel means which will now be described. As illustrated, each of the clamping arms 11 carries at its upper end and at the side thereof .L

which is nearer the toe end of the shoe a short depending ear 33 (Figs. 1 and 3) which is spaced somewhat from the side of the arm. A pin 35 is arranged to extend lengthwise of the shoe through the car 33 and into the arm 11 and has freely pivoted on it a carrier 37 for an overlaying member or wiper 39. The wiper 39 comprises a metal blade which may be, for example, about half an inch in width at its extreme inner end and about an eighth of an inch in thickness, and it projects 1 b ill) normally inward toward the location of the shoe somewhat farther than theupper-clamping pad 15, as indicated in Fig. 3. Formed integral with the outer end of 1 the wiper 39 is a block 41 which is mounted in .a guideway formedin the lower face of the carrier 37, this guideway extending inwardly toward the side of the shoe andsomewhat. also toward the toe end of the shoe; The outer end. of the blockel, which projects beyond the outer end of the carrier 37,is turned upwardly and has secured in it a rod 43 which extends inwardly into a bore formed in the carrier-37. above and parallel to "the above-mentioned guideway inthe carrier. -A light spring. 45 encircling the rod43 bears atits inner end on the outer. end of thecarrier 37 and at its outer end on the upturned end of the block ll and thereforetends to force thisblock and the wiper 39 outwardlyfrom theshoe; fFor limiting such outward movement of the block and wiper the wiper is provided with an upwardly extending ear 47 (Figs. 1, 2 and 3) in engagementwith the inner end of a plunger 49 which is housed in a tubular guide 51 extending inwardly toward the work support and. secured to an arm 53. This arm is generally similar in shape to the clamping arm 11 and is mounted on the same pivot 13 as thetclamping arm. A strong spring (Fig. 2) is housed in the guide 51 behind the plunger 49 and serves to force. the wiper 39 inwardly toward the shoe against-the resistance ofthe spring as when the arm 53 is moved in that. direction. The plunger 49 and the spring 55 are adjustable along the guideway in the member 51 to vary the initial positionof the wiper 39 by rotationof a sleeve 5'? which is threaded in the member 51. This sleeve serves as an abutment for the spring 55 and has therein abore through which extends a rod 58 that projects from the plunger 49. 1 i

The arin53 at each side of the. machine has formed .on its lower end an inwardly projecting gear sector 59 (Fig. 2) which meshes with gear teeth formed on a vertically movable rack bar 61. This rack bar is operatedpositively by a face cam 63 (Fig. 1) on the machine cam shaft 65 and by downward movement imparts inward swinging movements to the arms 53; their outward movements being effected by aspring (not shown). Each of the arms 53 has at its upper end an outwardly extending arm 67 which is curved about an axis concentric with the pivot 13 about which the arm 53 and thev clamping arm 11 are swung,- and in the outer end of the arm 67 there is secured 'a pin 69 having a rounded outer end extending into a guideway 71 formed the ad jacent clamping arm 11, this guideway being curved similarly tothe arm 67. A strong spring 73 located in the guideway 71 abuts at one end against: the pin 69 and thus serves'aspart of a yielding coupling between the. arm '53 and the clamping arm 11, so that inward swinging movement is imparted yieldingly to the arm 11 by correspondingmovement of the arm 53. r

It willbe. understood that in the operation of a-machine of the illustrated type, after the shoe upper and last have been correctly positioned in the machine with the margin of the upper materials between the open jaws of the grippers, the operator depresses a starting treadle and the grippersthereupon grip the margin of the upper and'jmove heightwise of the last to tension the upper over the last. After the grippers have finished their upper-pulling movements heightwise cfthe last, but before they release the upper, the arms'53 in the machine herein shown are swung inwardlyby downward movement of therack bar Gland through the springs 73 serve to swing the clamping arms 11. inwardly. Since the wipers 39 carried by the clamping arms 11 project inwardly somewhat beyond therubber pads 15, as hereinbeforedescribed, the inner ends of these wipers engage and press inwardly against the marginal portion of. the tensioned upper'in locations just below the level of the sole before the pads 15 and 17 .onthe clamping arms 11 arrive in upper-clamping positions. The wipers 39 are so positioned on the clamping arms that their inner ends engage the upper initially .in locations slightly nearer the heel end of the shoe than the portions of the upper that are engaged by the side grippers 9. While the grippers continue to hold the upper under tension the resistance of the upper preventsthe wipers 39 from being moved to. any substantial extent inwardly over the shoe bottom, as will be evident by reference to Fig. 5, and accordingly during further inward movements of the arms 53 after these wipers have engaged the upper the springs 55 which back up the plungers 49 yield so as to permit the wipers to remain substantially stationary while the pads 15 and 17 are carried into clamping engagement with the upper. The fact that the wipers are urged inwardly by spring plungers which are carried by the positively operated arms 53 and not by the clamp arms 11 relieves the springs 73 of the duty of moving both the wipers and the rubber pads into en gagement with the upper and of pressing them against the upper and therefore permits the pads to be forced more firmly against the upper than they otherwise would be. I

After the pads 15 and 17 on the clamping arms ll ha've engaged the upper and clamped it firmly against the last, and while the wipers 39 are pressing at their inner ends hard against the upper in locations slightly nearer the heel end of the shoe than the grippers 9, as hereinabove described, the tacker arms 23 and 31 are swung automatically inward toward positions for driving the upperholding tacl s upwardly into the shoe bottom. It will be understood thatas the tacker arms are swung inwardly in a machine of the illustrated type they are carried into engagement with memhere on the grippers which in response to such engagement cause the grippers to release the upper. Immediately upon such release of the upper by the grippers the wipers 39 are forced quickly inward over the shoe bottom by the springpressed plungers 19, thereby wiping the marginal portion of the upper inwardly over the sole as indicated in Figs.7 and 8. By reference to Fig. 8 it willbe seen that these wipers act on the upper in locations substantially at the ball portion of the shoe but farther from the toe end of the shoe than the rearmost side fastenings.

As the wipers 39 are forced inwardly over the 1 sole in themanner above described they serve to press the upper firmly against the bottom face of the sole. For this purpose there is associated with each wiper an upwardly extending spring- "pressed plunger 75 (Fig. 1) which is mounted in the upper end of the clamping arm 11.

This plunger bears at its lower end on the carrier 37 in a location farther from the work support than the pivot pin 35 about which this carrier swings,

so that the plunger serves to urge the inner end 'I of the wiper 39 in an upward direction. The plunger 75 is controlled by a spring 76 which bears at its upper end against a member 77 movable in the bore in which the plunger is mounted, and this member may be forced downwardly in the bore to increase the compression of the spring by a rotary hand lever device '79 having an ec'ct-intric portion bearing against the upper end of the member. Thus the upward pressure 5 with whichthe wipers 39 engage the upper may be varied. The inner ends of these wipers are turned downwardly somewhat so that they may ride easily over'the edge of the shoe bottom. A hooked member 81 carried by each clamping arm 1-0 11 has its lower end portion extending beneath a block on the carrier 37, as shown in Fig. 3, so as to limit movement of the carrier under the influence of the plunger 75. In order to position the inner ends of the wipers 39 properly heightwise of the shoe the members 81 are adjustable :heightwise of the shoe so as to adjust the carriers 37 about their pivot pins 35. Such adjustment of each member 81 is effected by a screw 87- which passes through a forwardly turned portion at the upper end of the member 81 and bears against the upper end of the clamping arm 11. To hold the member 81 in adjusted position there is provided a slot and bolt connection 89 between the member and the clamping arm.

Since the wipers 39 engage the upper in locations slightly nearer the heel end of the shoe than the grippers 9, they tend, when they first engage the upper held by these grippers, to defleet portions of the upper adjacent to the grippers lengthwise of the shoe toward its toe end, this tendency being increased by reason of the fact that the wipers as they move inwardly along the guideways in their carriers 37 have each a component of movement toward the toe end of the shoe. When the wipers are moved inwardly over the shoe bottom immediately upon the release or' the upper by the grippers, they have a further tendency to crowd the marginal portion of the upper engaged thereby toward the toe end of the shoe, after which they hold it clamped upon the sole while the tacks are driven. Each of the side tacker arms 31 also carries means for laying or wiping the marginal portion of the 'upper inwardly over the sole at the forepart, this means in the construction shown consisting of a wiper 85 having a single upper-engaging finger which acts in the inward movement of the tacker arm, after the grippers release the upper, to wipe inwardly over the sole a portion of the margin of the upper located slightly nearer the end of the toe than the corresponding side gripper '7 and nearer the end of the toe than the location of the foremost side fastening. Since, however, the wipers 39 are moved into engagement with "the upper earlier than the wipers 85 and are forced inwardly over the shoe bottom slightly in advance of the action of the wipers 85 on the upper when the grippers release the upper, and since also the wipers 39 are spaced substantial s, distances from the wipers 85, there is no danger of urging any excess of upper materials into the waist portion of the shoe and thereby rendering difiicult the later side-lasting operation, notwithstanding the fact that the wipers 85 have components of movement lengthwise of the shoe toward its heel end due to the directions of movement of the arms 31. When the several tacker arms have concluded their inward movements the upper-holding tacks are driven automatically and the shoe is then released by the machine.

By reference to Fig. 8 it will be seen that the inner ends of the wipers 39 are so shaped that at the end of their inward movements portions of them lie between the shoe bottom and those U tack holders in which the tack pockets 32 that are nearest the heel end of the shoe are located, the wipers thus engaging the upper in locations close to the locations where the tacks driven from these tack pockets enter the shoe. It will also be observed that the edges of the upper-engaging portions of these wipers which are toward the toe end of the shoe are disposed in such angular relations to the directions of inward movement of the wipers that they tend to crowd the marginal portion of the upper forwardly toward the toe'end of the shoe in the movements of the wipers over the shoe bottom.

While the machine herein shown is constructed especially to operate upon shoes of the McKay sewed type, the upper-fastening tacks being fully driven and clinched on a metal plate on the bottom of the last as illustrated in Fig. '7, it is to be understood that the invention is not limited to a machine of that particular character or that operates upon a shoe of that particular kind. It is also to be understood that the invention is not limited to a machine having the particular number of grippers and of fastening-inserting devices herein shown.
